Parking control device and parking control method

Abstract

A parking control device for a vehicle capable of non-contact power transmission between a first coil disposed in a parking space and a second coil provided in the vehicle, the parking control device includes: a parking control unit configured to execute parking control for automatically parking the vehicle in a target parking position where the first coil and the second coil face each other in the parking space; and a result detection unit configured to detect transmission result information of the non-contact power transmission executed at the target parking position. The parking control unit is configured to store, in a storage unit, parking position information during execution of the non-contact power transmission in association with the transmission result information each time the non-contact power transmission is executed in the parking space, and offset the target parking position based on past parking position information and the transmission result information stored.

What is claimed is: 
     
         1 . A parking control device for a vehicle capable of non-contact power transmission in which power is transmitted in a non-contact manner between a first coil disposed in a parking space and a second coil provided in the vehicle, the parking control device comprising:
 a parking control unit configured to execute parking control for automatically parking the vehicle in a target parking position where the first coil and the second coil face each other in the parking space; and   a result detection unit configured to detect transmission result information of the non-contact power transmission executed at the target parking position, wherein   the parking control unit is configured to
 store, in a storage unit, parking position information of the vehicle during execution of the non-contact power transmission in association with the transmission result information each time the non-contact power transmission is executed in the parking space, and 
 offset the target parking position of the parking control executed in the parking space based on past parking position information and the transmission result information stored in the storage unit. 
   
     
     
         2 . The parking control device according to  claim 1 , wherein
 the transmission result information includes at least one of a charging output and a charging efficiency, or at least one of a power feeding output and a power feeding efficiency, and   the parking control unit is configured to offset the target parking position of the parking control executed in the parking space to a position where at least one of the charging output and the charging efficiency, or at least one of the power feeding output and the power feeding efficiency is optimal.   
     
     
         3 . The parking control device according to  claim 1 , wherein
 the parking control unit is configured to
 offset the target parking position of the parking control executed in the parking space by a predetermined distance each time the non-contact power transmission is executed in the parking space, and store, in the storage unit, the parking position information in association with the transmission result information during execution of the non-contact power transmission, and 
 search for an optimal position for the non-contact power transmission in the parking space based on the parking position information and the transmission result information stored in the storage unit. 
   
     
     
         4 . The parking control device according to  claim 3 , wherein
 the parking control unit is configured to
 offset the target parking position in a first direction and search for a position in the first direction of the optimal position, and 
 after the position in the first direction of the optimal position is searched and set, offset the target parking position in a second direction perpendicular to the first direction and search for a position in the second direction of the optimal position. 
   
     
     
         5 . The parking control device according to  claim 3 , wherein
 the parking control unit is configured to simultaneously offset the target parking position in a first direction and a second direction perpendicular to the first direction, and search for a position in the first direction and a position in the second direction of the optimal position.   
     
     
         6 . A parking control method for a vehicle capable of non-contact power transmission in which power is transmitted in a non-contact manner between a first coil provided in a parking space and a second coil provided in the vehicle, the parking control method comprising:
 executing parking control for automatically parking the vehicle in a target parking position where the first coil and the second coil face each other in the parking space;   detecting transmission result information of the non-contact power transmission executed at the target parking position;   storing, in a storage unit, parking position information of the vehicle during execution of the non-contact power transmission in association with the transmission result information each time the non-contact power transmission is executed in the parking space; and   offsetting the target parking position of the parking control to be executed in the parking space next time based on past parking position information and the transmission result information stored in the storage unit.
